Diaqua-dichloridobis(pyridine-?N)manganese(II).

ABSTRACT: The molecular title compound, [MnCl(2)(C(5)H(5)N)(2)(H(2)O)(2)], lies about an inversion centre. The Mn(II) atom is in an all-trans octa-hedral environment defined by two water mol-ecules, two chloride anions and two pyridine ligands. An inter-molecular hydrogen-bonding inter-action between a water mol-ecule and a chloride anion bonded to an adjacent Mn(II) atom generates an eight-membered ring. The crystal packing exhibits two inter-molecular ?-? stacking inter-actions between the aromatic rings, with centroid-centroid distances of 3.485?(12) and 3.532?(12)?Å.

Diaqua-bis-(nitrato-?O)bis-(pyridine-?N)manganese(II).

Project description:The structure of the title manganese complex, [Mn(NO3)2(C5H5N)2(H2O)2], consists of discrete monomeric entities with Mn(2+) ions located on centres of inversion. The metal cation is octahedrally coordinated by a trans-N2O4 donor set with the pyridine N atoms located in the apical positions. Discrete mol-ecules are linked by O-H?O hydrogen bonds into one-dimensional supra-molecular infinite chains along the b and c axes.

Project description:In the title polymeric complex, [Mn(C(5)H(4)NO(3)S)(2)(H(2)O)(2)](n), the Mn atom is located on a centre of inversion and is coordinated by two O atoms and two N atoms derived from four different pyridine-3-sulfonate (pySO(3)) ligands, and two O atoms derived from two water mol-ecules in a distorted trans-N(2)O(4) octa-hedral geometry. The metal atoms are bridged by the pySO(3) ligands to form a one-dimensional chain. The chains are further connected into a three-dimensional architecture via hydrogen bonds.

Diaqua-bis-(pyridine-2-carboxyl-ato-κN,O)manganese(II) dimethyl-formamide hemisolvate.

Project description:There are two crystallographically independent complex mol-ecules with very similar geometries in the unit cell of the title compound, [Mn(C(6)H(4)NO(2))(2)(H(2)O)(2)]·0.5C(3)H(7)NO. The central ion is situated in a distorted octa-hedral environment of two N- and four O-donor atoms from two pyridine-2-carboxyl-ate ligands and two cis-disposed water mol-ecules. The carboxyl-ate ligands are coordinated in a chelate fashion with the formation of two five-membered rings. In the crystal, the complex mol-ecules are connected by O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the uncoordinated carboxyl-ate O atoms, thus forming hydrogen-bonded walls disposed perpendicularly to the bc plane.

catena-Poly[[diaqua-manganese(II)]-?-pyridine-2,4,6-tricarboxyl-ato-?N,O,O:O,O].

Project description:In the title compound, [Mn(C(8)H(2)NO(6))(H(2)O)(2)](n), each pyridine-2,4,6-tricarboxyl-ate (tpc) ligand bridges two Mn(II) ions with the formation of polymeric chains located on a twofold rotation axis. Each Mn(II) ion is coordinated by two O and one N atoms from one tpc ligand, two O atoms from another ligand and two water mol-ecules in a distorted penta-gonal-bipyramidal geometry. The Mn-N [2.243?(2)?Å] and Mn-O [2.206?(2)-2.3123?(16)?Å] bond lengths are normal. The coordinated water mol-ecules link neighbouring polymeric chains via O-H?O hydrogen bonds into a two-dimensional framework parallel to the bc plane.

Diaqua-dichloridobis[quinazolin-4(1H)-one-?N]copper(II).

Project description:In the title complex, [CuCl(2)(C(8)H(6)N(2)O)(2)(H(2)O)(2)], the Cu(II) ion is located on an inversion center and is octahedrally coordinated by two N atoms of the 1H-quinazolin-4-one ligand, two chloride ligands and two aqua ligands. The axial Cu-O distances are significantly longer [2.512?(2)?Å], than the Cu-N [2.022?(2)?Å] and Cu-Cl [2.3232?(4)?Å] distances as a result of Jahn-Teller distortion. Aqua ligands are involved in intra- and inter-molecular hydrogen bonding, and N-H?O inter-molecular hydrogen bonds are formed between the organic ligands. In addition, weak ?-? inter-actions are observed between the benzene rings of the ligand [centroid-centroid distance = 3.678?(1)?Å].

catena-Poly[[[diaqua-manganese(II)]-?(3)-pyridine-2,3-dicarboxyl-ato-?N,O:O:O] dihydrate].

Project description:In the title coordination polymer, {[Mn(C(7)H(3)NO(4))(H(2)O)(2)]·2H(2)O}(n), the Mn(II) ion is coordinated in a distorted octahedral environment by the O atoms of two water mol-ecules, one N and one O atoms of the chelating pyridine-2,3-dicarboxyl-ate (PDC) dianion, and two axial bridging carboxyl-ate O atoms from two adjacent PDC ligands. The fully deprotonated PDC anion acts a ?(3)-bridging ligand, establishing a chain structure along the a axis. These polymeric chains are connected into a three-dimensional framework via several inter-molecular O-H?O hydrogen bonds.

Project description:In the title complex, cis-[PtCl(2)(C(11)H(9)N)(2)], the Pt(II) ion is situated in a slightly distorted square-planar environment coordinated by two N atoms from two 2-phenyl-pyridine ligands and two Cl atoms. The two pyridyl planes are inclined with dihedral angles of 59.1?(2) and 61.84?(19)° with respect to the PtCl(2)N(2) plane. In the crystal, the complex mol-ecules display inter- and intra-molecular ?-? stacking inter-actions, with centroid-centroid distances of 3.806?(5)-3.845?(5)?Å, which form a one-dimensional column structure along the a axis.

Project description:The asymmetric unit of the title complex, [PdCl(2)(C(11)H(9)N)(2)], contains one half of a neutral Pd(II) complex, with the complete mol-ecule generated by the application of a twofold rotation axis; the N-Pd-N atoms lie on the axis. The Pd(II) ion has a trans-Cl(2)N(2) square-planar coordination geometry defined by two N atoms from two 4-phenyl-pyridine ligands and two Cl(-) anions. In the refinement, the pyridine ring and the phenyl ring were found to be disordered over two sites with the site-occupancy factors being 0.53 (2) and 0.51 (1), respectively, for the major components.

Project description:In the title complex, [NiCl(2)(C(8)H(6)N(2)O)(2)(H(2)O)(2)], the Ni(II) ion is located on an inversion center and is six-coordinated by two N atoms of 1H-quinazolin-4-one ligands, two chloride ions and two water mol-ecules. The water mol-ecules are involved in intra- and inter-molecular O-H?O and O-H?Cl hydrogen bonding. Inter-molecular N-H?O and N-H?Cl hydrogen bonds are formed between ligands. In addition, weak ?-? inter-actions are observed between the benzene rings of the ligands [centroid-centroid distance = 3.580?(3)?Å]. The inter-molecular hydrogen bonds and ?-? inter-actions lead to the formation of a three-dimensional supra-molecular network.

Project description:The title compound, LiMn(H(2)O)(2)[BP(2)O(8)]·H(2)O, is built up of an open framework of helical borophosphate ribbons inter-connected by MnO(4)(H(2)O)(2) octa-hedra, forming one-dimensional channels along [001] occupied by Li(+) cations and disordered H(2)O mol-ecules (site occupancy 0.5). The Li cations reside in two partially occupied sites [occupancies = 0.42 (3) and 0.289 (13)] near the helices.
